TUNING-PEG FOR STRENGED INSTRU'MENTS.

Specification of Letters Patent Application filed July 25, 1907.

Patented April 20, 1209.

Serial No. 385,563.

To all whom it may concern:

7 Be it known that l, Hans HAUBNER, a subject of the Emperor of Austria-H ingary, rcsiding at Marienbad, Bohemia, Austria-flungary, have invented certain new and useful Improvements in 'luningfegs l'or Stringed Instruments; and I do hereby declare the ro llowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tuning pegs for stringed instruments in which the peg is nested through a ratchet with a worm 7 the peg being operated direct by a tun ngkey to approximately adjust the string which is finally brought to the correct pitch by turning the worm of the worm gear. In known tuning devices of this kind the ratchet COD- is arranged in the hub of the worm-wheel.

which is made hollow. This arrangement causes a weakening of the parts which are put under strain when the string is tensioned so that these parts are very liable to break. Moreover the ratchet is controlled by a device that is carried through the peg, is inconvenient to 0 erate and, when turned, is liable to damage the locking-parts One example ol' the invention is illustrated in the accompanying drawing in which- Figure 1 is a side elevation of the tuning device. Fig. 2 an end elevation of the wormwheel gear. 3 shows the engagement oi the locking wheel on the peg with the worm wheel. Figs. l and 5 are plans oi the worm wheel and of the locking a heel.

T e peg a has a boring b for receiving the string in the usual manner and is seated in the neck of the instrument and passes through the center oi the worrn-wheel (Z which is loose on peg o. The worinovheel (Z is operated by a worm g, which is rotated by hand through the medium of a fiat head 7L. On the peg a, on the outside ol the worm-wheel, a toothed sliding collar Z is arranged to slide along the peg. The neck of the peg is provided with a linger piece or knob 75 which enables the peg to be turned by hand. On the neck of the peg spring m is coiled, by means or" which the toothed collar 1 is held in engagement with teeth n arranged on the worm-wheel (Z. YJhen the final tuning is effected the wornr g is rotated by means of the head It, whereby the worm-wheel (Z is operated. E'rs the wheel (Z is coupled with the peg a through the collar Z the peg a is also rotated, so that the string wound on the peg and thereby put under tcnsitn in tho prcl inary ten sicning of the string the peg (z is rotated directly by means oi the handle 7;, the t er/Q on the collar Z sliding over the teeth a o" the wornewhcel d, without actuating the wheel. A slackening oi the string can be effected by turning the. peg backward. by means of the handle Zr, the collar Z being put out of engagement by sliding it along the peg against the spring To. fhe peg a can t l en turn ireery so that it is easy to remove a broken string.

H hat I claim and desire to secure by Letters Patent is:

in a tuning device for stringed instruments the combination of handle or tuning key, a peg adapted to be rotated by means ol' the handle or tuning key, with a wornnwheel through the hub of which the peg is passed, a worm that acts in combination with the worm wheel, clutch collar, arranged to slide 'l'ieely along the peg on the outside of the wor- 1 wheel and to lock the WOl'll'i wheel to the a set of ratchet teeth on the worm and a spring adapted to hold the whee whiten collar in engagem nt with the teeth on the worm wheel.

In testimony whereof I have aihxed my signature, in presence of two witnesses.
